WSK-MLT MULTIFUNCTION WALL SWITCH

- INSTALLATION AND OPERATING INSTRUCTIONS -

Introduction

The WSK-MLT multifunctional wall switch is designed to control ﬂ ame height, blower speed, and auxiliary functions on your gas fireplace. For models equipped with the Intelliﬁ re system (IPI), the cold climate function can control the pilot ﬂ ame as well. The wall switch is equipped with thermostat functions which can automatically control the temperature in the room in which it is installed. The wall switch interfaces with both intermittent and standing pilot systems. An auxiliary function provides 110-120 VAC source for added features the ﬁ replace may have installed. Electrical ratings for the control box are 110 VAC, 60 Hz, and is required for operation of this device.

Installation precautions

This remote is tested and safe when installed in accordance with this installation manual. It is your responsibility to read all instructions before starting installation and to follow these instructions carefully during installation. Do not install any components that may be damaged. Do not modify, disassemble, or substitute any of the components included with this kit. Installation of this unit must be done by a qualiﬁ ed service technician.

Placement of this wall switch may affect performance or accuracy of the automatic (thermostat) control. An assessment of the space should be done prior to installation for optimal performance. See the installation instructions section I for recommendations.

NOTE: The electrical junction box provided with the ﬁ replace must be wired with 110 VAC before installing this kit. See owners manual for details.

1.0 Installation instructions

1.1 Determine location

Determine the location for the wall switch. The chosen location should provide an accessible location in the same space as the gas ﬁ replace. Never place this unit in a separate room. The control wire supplied with this switch is 33 ft (10M) in length. The distance from the ﬁ replace to the switch may be lengthened provided that the wire used never exceeds 50 ft, and that the distance from the ﬁ replace to the switch never exceeds 30 ft.

All wiring should be done by a qualiﬁ ed electrician and shall be in compliance with local codes and with the National Electric Code ANSI/NFGA No. 70- current (in the United States), or with the current CSA C22.1 CANADIAN ELECTRIC CODE (in Canada).

WARNING

Shock Hazard Do not provide any power to this unit until all

wiring is completed. Failure to do so may destroy parts of this device and render it unusable, and may lead to possible electrical shock.

Fire Hazard Modification of any parts or installation of

damaged components will void the warranty, and you may possibly cause a ﬁ re hazard.

The switch should be mounted into a listed electrical junction box. The junction box should be dedicated to this wall switch. Never install this wall switch into a junction box that is shared with other electrical service or devices. If possible, install this unit on an interior wall of the residence at a recommended height of 5 ft from the ﬂ ooring. Should the switch be installed on an exterior wall, be certain wall insulation is kept intact and not damaged or dislodged during the installation of the electrical junction box.

For exterior wall installations, it is recommended that the junction box be sealed with caulking material. This will minimize heat loss through this location and improve the accuracy of the automatic (thermostat) operation.

1.2 Wiring the wall switch

Once a location is chosen and the electrical box is installed proceed as follows. Install the provided control wire from the ﬁ replace to the switch location. (Control wire for Heatilator products is supplied with the ﬁ replace). Use caution not to stress the wire around tight or sharp corners. Do not run the control wire adjacent to existing or future phone, data, cable, or electrical lines. The wire should not come into contact with any part of the ﬁ replace exterior with the exception of where it exits the outer wrap. Feed the wire

to the electrical junction box and through a provided or approved strain relief. Using a screw driver, connect the red wire to the “R” terminal, the yellow or white wire to the “W” or “Y” terminal, and the green wire to the “G” terminal. Do not over-tighten. Using the screws provided, mount the switch to the electrical junction box right side up. Install provided cover plate using the screws provided. Do not use a substitute cover even though it may ﬁ t. The provided one is speciﬁ cally designed for the automatic (thermostat)

function of the unit.

1.3 Installing the control box

CAUTION

• Do NOT install the control box when ﬁ replace is hot.

• Do NOT plug control box in until all connections are complete.

1. Place control box into the base pan area of the ﬁ replace. Place unit as close to the louvers or decorative front as possible and to either the left or right side.

2. Connect the red, yellow or white, and green wires to the appropriate labeled terminals on the control box.

For units WITH factory installed rocker switch.

3. Find the red and brown pigtail wire (labeled “ FOR USE WITH REMOTE OR WALL SWITCH ONL Y”) which are attached to the ﬁ replace ON/OFF rocker switch.

Standing Pilot Ignition: Connect these wires with the

red and brown wires extending from control box (Fig 2).

Intelliﬁ re (IPI): Connect these wires with the brown

wires extending from the control box (see Figure 3).

For units WITHOUT factory installed rocker switch.

Standing Pilot Ignition: Find these parts packed with WSK-MLT:

• Rocker switch

• Rocker switch bracket

• Strips of Velcro

• Black and white wire pigtails - (2)

• Female ends (only used on Standing Pilot applications) - (2)

Cut male ends off black wires on each pigtail. Strip each end of wire approximately 1/4 inch. Slide each stripped wire into a female end and crimp. Slide rocker switch into bracket until it snaps into place. Attach end of each pigtail to each side of rocker switch. Find the top (brown) and bottom (red) wires from the control box and attach to white wires from rocker switch. Attach one black wire to the TH/TP side of gas valve and the other to the TH side of the gas valve. Attach the Velcro to the bottom of the rocker switch bracket and mount in a convenient location next to gas valve. (Refer to Figure 4).
